Joana Dumčiūtė,Vytas Martynaitis,Wolfgang Holzer,Sven Mangelinckx,Norbert De Kimpe,Algirdas Šačkus +5 more
TL;DR: In this paper, the five-membered heterocycle 1-amino-1,2,3,9a-tetrahydroimidazo[1, 2, a ]indol-2(9 H )-one was reported.
Journal ArticleDOI
Synthesis of 3-substituted 1-phenyl-1H-pyrazole-4-carbaldehydes and the corresponding ethanones by Pd-catalysed cross-coupling reactions
TL;DR: In this article, an efficient synthetic route to construct ortho-substituted 1-phenyl-1H-pyrazole-4carboxaldehydes and the corresponding ethanones starting from 1phenyl 1H pyrazol-3-ol is described.
Journal ArticleDOI
Synthesis of electroactive hydrazones derived from 3-(10-alkyl-10H-phenothiazin-3-yl)-2-propenals and their corresponding 3,3′-bispropenals

TL;DR: In this paper, a previously unexplored class of functionalised phenothiazine derivatives were prepared upon reacting N-alkylated 3-bromo- and 3,7-dibromo,10H-phenothiazines with acrolein diethyl acetal under Pd catalysis.
Journal ArticleDOI
Optically controlled molecular switching of an indolobenzoxazine-type photochromic compound.
Kipras Redeckas,Vladislava Voiciuk,Rasa Steponavičiu̅tė,Vytas Martynaitis,Algirdas Šačkus,Mikas Vengris +5 more
TL;DR: Two possible models, involving the S1 excited state of the terminal photoproduct and its hot ground state, are introduced to explain the pre- and post-reexcitation spectral development and the photoinduced switching back mechanics.
Journal ArticleDOI
On the Tautomerism of N-Substituted Pyrazolones: 1,2-Dihydro-3H-pyrazol-3-ones versus 1H-Pyrazol-3-ols
Eglė Arbačiauskienė,Sonata Krikštolaitytė,Aiva Mitrulevičienė,Aurimas Bieliauskas,Vytas Martynaitis,Matthias Bechmann,Alexander Roller,Algirdas Šačkus,Wolfgang Holzer +8 more
TL;DR: Comparison of NMR (nuclear magnetic resonance) spectra in liquid state with those of “fixed” derivatives, as well as with the corresponding solid state NMR spectra reveal this compound to exist predominantly as 1H-pyrazol-3-ol molecule pairs in nonpolar solvents like CDCl3 or C6D6, whereas in DMSO-d6 the corresponding monomers are at hand.
